Passive House - Bushfire Attack Level Flame Zone

'Passive' home more expensive to build but cheaper to run, achieves highest bushfire risk rating.

Australia's first passive house built to the highest bushfire rating has been unveiled in the midst of an early start to the bushfire season, as experts gather to advise residents on fire safety.

  • Home builders have designed and built an eco-friendly passive home that meets the development requirements for the highest bushfire risk rating
  • The energy-efficient home costs $3.80 a day to power, but construction costs were 22 per cent higher than a standard build
  • A bushfire architecture consultant said building bush homes partially underground could be the future for fire protection

When Joe and Merylese Mercieca began building solar passive homes 15 years ago, architects, suppliers, and contractors told them it would not work.
Without the available solar technology, the Merciecas were able to achieve a solar passive rating by thinking creatively and adapting commercial products for residential builds.
"So we proved everybody wrong 15 years ago … [and] we're doing it again today," Mr Mercieca said.
Their latest creation is Australia's first passive house to meet the development requirements for the highest bushfire risk rating — Bushfire Attack Level Flame Zone (BAL-FZ).
